The Seahawks made a couple of changes to their initial 53-man roster on Monday, re-signing fullback/defensive tackle Tani Tupou, who was waived Saturday as part of the team's roster cuts. A spot was open on the 53-man roster because Saturday's trade with San Francisco for safety L.J. McCray was rescinded due to trade conditions not being satisfied. Tupou, a defensive lineman at the University of Washington, has played both fullback and defensive tackle with the Seahawks since signing as an undrafted rookie free agent.

Seattle also claimed defensive tackle Garrison Smith after the San Francisco 49ers waived him as part of their roster cuts. Smith, who is 6-foot-1, 300 pounds, was one of San Francisco's preseason standouts, recording 15 tackles, 5 tackles for loss and 2 sacks. Defensive tackle Justin Hamilton was waived to make room on the 53-man roster. Smith will provide depth at a position that has been affected by injuries, with both Sealver Siliga and Jordan Hill landing on injured reserve—Siliga has since been released from injured reserve with an injury settlement. Smith went undrafted out of Georgia in 2014, and has spent time with the Miami Dolphins, New Orleans Saints and 49ers on their practice squads. Hamilton first signed with Seattle in 2015 as part of the Seahawks' practice squad, then signed a futures contract with Seattle at the end of the season.

Additionally, the Seahawks signed eight players to their practice squad: defensive end Tylor Harris, receiver Kenny Lawler, linebacker Kache Palacio, guard/center Will Pericak, receiver Kasen Williams, receiver Rodney Smith, receiver Marcus Lucas and linebacker Jordan Tripp. Harris, Lawler, Palacio, Pericak and Williams were part of Seattle's 75-man roster ahead of Saturday's cuts.

Smith, who is 6-foot-5, 225 pounds, went undrafted out of Florida State in 2013, and has spent time with Minnesota, Cleveland and Dallas over the past three seasons, appearing in seven games. Tripp, a fifth-round pick in 2014 out of Montana, has spent time with Miami and Jacksonville, appearing in 25 games, starting one. Lucas, who went undrafted out of Missouri in 2014, has spent time with Carolina, Miami and Chicago.

Defensive ends David Perkins and Josh Shirley, meanwhile, were waived from injured reserve.
